BharatNotes What is Marginal Standing Facility?
The Marginal Standing Facility (MSF) is a Reserve Bank of India (RBI) window through which scheduled commercial banks can borrow money overnight in an emergency, over and above what they can raise via the normal Liquidity Adjustment Facility (LAF) repo route. Its defining feature is that banks may borrow by dipping into their Statutory Liquidity Ratio (SLR) securities — i.e., pledging government securities they otherwise hold to meet the SLR requirement.
MSF was introduced in the RBI's 2011-12 Monetary Policy (effective 9 May 2011) to provide an assured liquidity safety valve and to reduce volatility in the overnight call money rate. Because it is a last-resort facility, MSF is priced at a penal rate above the repo rate.
Key Features
| Feature | Detail (as of June 2026) |
|---|---|
| Tenor | Overnight (next working day repayment) |
| Eligible borrowers | Scheduled commercial banks (excluding Regional Rural Banks) |
| Rate | 5.50% — fixed at repo rate (5.25%) + 25 basis points |
| Collateral | SLR-eligible government securities (banks may dip into SLR) |
| Borrowing limit | Up to 2% of Net Demand and Time Liabilities (NDTL); raised from the original 1% |
| Minimum bid | Rs. 1 crore, in multiples of Rs. 1 crore |
| Role in corridor | Upper bound (ceiling) of the LAF corridor |
During the COVID-19 stress, the RBI temporarily allowed banks to borrow up to 3% of NDTL under MSF; this enhanced limit was later rolled back to the standard level.
Significance in the LAF Corridor
The RBI operates an interest-rate corridor to keep the overnight money market rate near the policy repo rate:
- Ceiling: MSF rate (repo + 25 bps) — banks borrow here when short of funds.
- Centre: Policy repo rate — the benchmark policy rate.
- Floor: Standing Deposit Facility (SDF) rate (repo - 25 bps) — where banks park surplus funds.
Whenever the Monetary Policy Committee (MPC) changes the repo rate, the MSF rate moves automatically to maintain the +25 bps spread. The Bank Rate is aligned with the MSF rate and therefore also stands at 5.50% (as of June 2026). This symmetry keeps the weighted average call rate anchored within a predictable band, strengthening monetary policy transmission.
Current Status (June 2026)
At the June 2026 MPC review, the RBI kept the policy repo rate unchanged at 5.25%, leaving the MSF rate at 5.50% and the SDF at 5.00% — a 50 bps corridor. The Bank Rate stands aligned at 5.50%.
UPSC Angle
MSF is best learned alongside the full corridor. A common Prelims trap is confusing MSF (the ceiling, which permits dipping into SLR) with the SDF (the floor, which is uncollateralised). Remember the structural rule: MSF = repo + 25 bps; SDF = repo - 25 bps. For Mains GS3, MSF is useful when discussing how the RBI manages liquidity and transmits rate signals. As a foundation concept it underpins broader questions on monetary policy tools, inflation targeting, and the operating framework of the central bank.
